PETER J. FOULON, OF NEW YORK, ASSIGNOR OF ONE-HALF To GEORGE E.

CONSTANTINE, or BROOKLYN, NEW YORK.

ARGAND LAMP-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 404,474, dated June 4, 1889.

Application filed Decembe 7- To all whom it may concern.-

Be it known that I, PETER J. FoULoN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Argand Lamp-Burners, of which the following is a specification.

My invention relates especially to that class to of lamp-burners for which I filed an application for Letters Patent April 23, 1887, Serial No. 236,233, patented September 4,1888,- No. 389,068; and it consists of certain details of construction, hereinafter described, for pror 5 moting the efficiency of the stop servingto regulate the motionof the wick-carrier; also of the air-space on theupperend oflthe wicktube, the air-distributer, and other parts.

In the accompanying drawings, Figure 1 represents a vertical central section of a lampburner embodying my invention. Fig. 2 represents a horizontal section thereof on the line w m, Fig. 1, omitting some of the parts. Fig. 3 represents a side view of the wick-carrier z 5 detached. Figs. 4 and 5 represent detail views of parts. Fig. 6 represents a cross-section of the inner wick-tube and wick-carrier. Fig.

7 represents a side view of a portion of said tube. I

Similar letters indicate similar parts. The letter A indicates the shell of the burner, perforated, as usual, for the admission of air, which thence passes upward around an outer tube 13, surrounding the wick, said shell 3 5 being left entirely open for that purpose, as

well as through transverse tubes 0, to the in- .her or wick tube D, said inner and outer tubes being connected together by the transverse tubes.

The letter F indicates the wick-carrier, and

G a combined spreader and extinguisher,

which parts are provided with racks F and G, respectively, engaging with spirallythreaded disks F and G respectively, in

such amanner that when said disks are turned in one or the other direction the wick-carrier or the spreader and extinguisher are raised or lowered, as the case may be. The

wick-carrier is also provided with two arms I,

Serial No. 257,070. (No model.)

N, which also extends through one of the transverse airt-ubes C and shell A to the outside of the burner, where it is provided with a finger-button N, and on the inner end of Whichis fitteda non-rotating nut N so that by turning said rod in the proper direction for tightening the nut the stop-arm may be secured in-any desired position, said upper slot of the arm permitting it to be adjusted in vertical direction.

Into the lower slot K of the stop-arm is fitted a stop-pin O, which projectsfrom the bridge I of the wick-carrier in such a mannor that when said carrier is moved either upward or downward it is arrested by the contact of the pin with the ends of the slot, so that the pin and slot serve to regulate both the upper and lower position of the wick-carrier and wick, the object being to provide for both a fixed burning-point and fixed extinguishing-point, to adjust which it is only necessary to properly adjust the stop-arm.

On the upper end of the wick-tube D is fitted a 'ring P, which is held in position by a shoulder P, formed in said tube next to the lower edge of the ring, and by a flange P formed on the upper end of the tube and next to the upper edge of the ring. The inner diameter of the ring P is slightly greater than the portion of the wick-tube on which itis fitted, so that a space or chamber is left he tween the ring and'tube for the effective cir culation of air, which tends to decrease the heat-conducting property of the tube.

Into each of the transverse air-tubes connecting the inner and outer tubes 13 D is fitted a diaphragm Q, (one or more,) of-wirewhich project downwardly from a wick-ring 5o gauze or other similar material, to form a strainer or distributer for the air passing through said tubes to the wick-tube D, the diaphragm being simply forced into the tubes and held in place by friction. Said arrange ment of the air-distributor Q, in the transverse air tubes or passages has the effect of reducing the pressure of the air entering the wick-tube D and to admit only a fixed quantity of air to said tube, thereby producing a steady flame. An air-distributer Q may also be fitted in the wick-tube D at or near its upper end, and around the outer tube B, as at T, between it and theshell of the burner.

The wick-raising rack F is left free on its upper part or end, and in order to guide or support said end thereof an arm S is secured to the upper part of the spreader-rack G, to thence extend downwardly in rear of the wick-raising rack, said arm having flanges S on the edges to embrace both edges of said rack, as shown in Fig. 3.

In the example shown the spreader-operating disk G2 is movable lengthwise of the shaft, and when it is so arranged the arm S also acts as a support therefor to hold it in gear with the spreader-rack.

The cone U of the burner is of the usual form, and is preferably united to the top of the shell A by a bayonet-joint, and a corre sponding joint is preferably used to connect the parts or sections of the outer wick-tube 13. A screw-collar V is united to the lower part or ring A of the shell, and said ring is perforated with a circular row of holes at a point within the screw-collar, the latter being left entirely solid, so that a portion of the air entering the shell is admitted to the fouut of the lamp through the collar, for cooling the oil, together with the fount.

It is evident that the air-distributers Q, may be fitted on the transverse tubes 0, interior or exterior thereof, instead of into said tubes, with a like effect.

In the exterior of the inner wick-tubeD are longitudinal grooves D, and in the upper portion or ring I of the wick-carrier are spurs I which project inwardly therefrom into said grooves and work therein, thereby guiding the wick-carrier in vertical direction and preventing it from turning. One or more of said leaving the metal solid.

grooves D and spurs I may be used, and they are struck up in the sheet metal composing the parts by means of suitable dies, For the purpose of holding the nut N of the screw-rod against rotating, it is arranged adjacent to the lower closed end I) of the inner wick-tube, as shown in Fig. 1, thereby contacting by one of its flat sides with said end of the tube.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In an Argand burner, the combination of the stop-arm having two vertical slots, the screw-rod fitted into one of said slots for adjustably connecting the stop-arm to a fixed portion of the burner, and the wick-carrier having a stop-pin fitted into the other of said slots for regulating the motion of said carrier, substantially as and for the purpose described."

2. In an Argand burner, the combination, with the wick-tube, of a ring fitted thereon with an air space or chamber between said tube and the ring, substantially as and for the purpose described.

3. In an Argand burner, the combination, with a wick-tube having a flange on the upper end, and a shoulder below said end, of a ring fitted loosely on said tube between said flange and shoulder, substantially as and for the purpose described.

4. In an Argand burner, the combination,

with the open perforated shell, the inner and outer tubes, and the transverse tubes connecting the same, of the air-distributors fitted into or on said transverse tubes, substantially asand for the purpose described.

5. In an Argand burner, the combination, with a wick-carrier havingan attached rack, which is left free on the upper end, as shown, of a spreader and extinguisher, also having an attached rack, and an arm secured to said spreader-rack to form a guide or support for the wick-rack, substantially as described.

Signed at New York, in the county of New York and State of New York, this 30th day of November, A. D. 1887.
